I run a Trackstar V2 7.5t Its pretty smooth. I wonder if the OP has a radio adjustment wrong. positive throttle curve or something else. I can't remember the name of the setting but I had a friend with a Futaba 4px and it had some acceleration or something on the throttle channel. So you would just touch the throttle and it would take off like a rocket.
